Sorry to see that happen to you.
As a tech person though, here's what you should do:
Don't reallocate that drive. Don't use that drive anymore.
it doing what it did likely means it's on it's way to permanent failure.
If you don't format it you can likely try and get most of what was on it off of it, but the important thing would be to get a new drive. If you want to go down the road of trying to get data off of it, shoot me a message and I'll do my best to send you some links to tools I've used in the past.
Thankfully it's not really possible for Cyberdrop-DL to fail catastrophically enough to do that.
